ANTI-SKID nnvroa.

Application filed March 20, 1923. ,sria1 No. 626,343. A

To all whom it may concern:

Be it known that I, ALLEN B. HUSEUI'ON, a citizen of the United States,residing at Butler, in thecounty of Butler and State of Pennsylvania,have invented certain new and useful Improvements in Antiskid Devices;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a traction or anti-skid device for vehiclewheels and especially those equipped with pneumatic tires.

It is aimed to provide a novel construction which will withstand maximumwear and yet afl'ord eflicient traction, and one which has adjustablemeans toenable it to grip tires of different sizes and also to preventrelease of the fastening means.

In addition it is aimed to provide a novel construction of shoe and calkcarried there- Additional objects and advantages will become apparentfrom a consideration of the description following taken in connectionwith accompanying drawings illustrating an operative embodiment.

In said drawings Figure l is a side elevation of a vehicle wheel showingthe device in place;

Figure 2 is a plan view of one of the shoes,

Figure 3 is a perspective view of one of the shoes,

Figure 4 is a perspective view of one of the calks,

Figure 5 is a detail perspective view illustrating one of the hook andlink connections, and

Figure 6 is a detail perspective View of the tool preferably used tofasten and unfasten the hooks and links.

Like reference characters designate like or similar parts in thedifi'erent Views.

In carrying the invention into practice, any suitable number of shoes 1are provided, for instance ten, preferably of metal, and curvedlongitudinally and transversely to conform to the exterior shape of atire such as that shown at A mounted on an automobile or other vehiclewheel B. Each rable engagement with endless links pivoted in'theopenings of adjacent cars. Turn buckles 5 connect the remaining-ears ofadjacent shoes l together. These turn buckles are of any suitableconstruction for instance having bolts 6 pivotally connected in openings7 of the ears and screw threaded forengagement with the opposite screwthreads of the end portions of nuts 8 of the buckle grips or frames 9.As a result of thiscondental detachment of the hooks 3 and links 4.

The

turn buckles being loosened, the hooks 3 may be readily disconnectedfrom the links 4. In applying the chain to a tire casing, the operationis reverse and the hooks 3 are engaged with the links 4 and the turnbuckles are then tightened, using the implement shown in Figure 6, inorder to obtain a leverage. 7

Calks or traction devices, preferably metallic, and capable of beingcast in a single piece, are shown at 12. These calks consist oflongitudinal bars 13 having transverse branches 14 at suitableintervals. At the junctions or corners of the bars 13 and branches 14,webs 15 are provided to reinforce the calks and also form a fasteningmeans. These webs 15 are of considerably less thickness than the bars 13and branches 14. Rivets or other fastenings 16 may be passed throughcertain of the webs 15 and shoes 1 in order to secure them to ether. Atleast six rivets are usually use for each calk and shoe.

As the calks may be readily cast in a single piece, they are inexpensiveand in addition their form afi'ords considerablev traction and they aregenerally reinforced by the webs 15 which function also as fastoning.means. The rivets may be readily removed in order to accommodate thesubstitution of new calks and rivets Whenever desired.

The shoes for example may be made from malleable iron While the calksare adapted to be cast from steel. 7 v

As merely one operative embodiment has been illustrated and described,it is to be understood that changes in the details may be resorted toprovided they fall Within the spirit and scope of the invention.

51 claim as my invention 1. A traction device adapted to surround aWheel including shoes, each shoe having a pair of ears at each sidethereof, hooks in certain of said ears, loops separately engageable' bysaid hooks carried by certain other ears, and the remaining ears beingjoined by turn buckles, said turn buckles being operable 'to contractthe device to fit a tire and to prevent disengagement of said hooks andloops. 2. A traction device including a shoe for application against atire, a calk on said shoe, said oalk having a main bar and branchesextending therefrom, Webs integral with the main bar and branches, andfasten- ALLEN B.
